This is one of the major symptoms of Diabetes type 2. A diabetic person may feel worn out because his body cells are unable to absorb glucose from the blood stream. Glucose is a main energy source for almost all the body cells and insulin does the job of helping cells to absorb glucose from the bloodstream. Insulin resistance is developed in type 2 diabetes leading to lack of glucose absorption in the cells. This eventually cause fatigue and tiredness. In these circumstances, you must get your blood tests done as soon as possible to reveal the actual cause of your tiredness.
Type 2 diabetes patients commonly suffer from “Chronic Fatigue Syndrome” in which person feel tired all the time and fatigue does not go away even with adequate rest. Poor circulation in the type 2 diabetes patient can also be a major cause of fatigue as nutrients and electrolytes can not reach tissues sufficiently.
